I have some stuff written about using two ivtv cards. (One PVR-250 and on 
M179, to be specific).

Look at the output of dmesg after loading up the ivtv module. The 350 will be 
discovered as an iTVC15 card. However, so will an M179 and a rev1 PVR-250, 
but if you have a rev2 PVR-250, it'll show up as an iTVC16 card, like so:

# /bin/dmesg |grep ivtv
ivtv: Found an iTVC16 based chip
tuner: probing ivtv i2c driver #0 i2c adapter [id=0x10005]
saa7114.c: starting probe for adapter ivtv i2c driver #0 (0x10005)
ivtv: Encoder revision: 0x02040011
ivtv: Registered v4l2 device, minor 0
ivtv: Registered v4l2 device, minor 32
ivtv: Registered v4l2 device, minor 224

The pertinent section from my modules.conf for a PVR-250 and M179:

# ivtv modules setup
alias char-major-81 videodev
alias char-major-81-0 ivtv
alias char-major-81-1 ivtv
options tuner type=2
options msp3400 once=1 simple=1
add below ivtv msp3400 saa7115 tuner

Just add the misc other bits for PVR-350 output to that if you're going to use

That one, I dunno...

Your assumption is correct, it really isn't too difficult.
